1. A forceps, comprising:
a housing defining an internal passageway and a longitudinal axis extending between proximal and distal ends of the housing;
a first jaw slidably and pivotably connected to the housing;
a second jaw slidably and pivotably connected to the housing, wherein the first and second jaws have an open configuration and a closed configuration;
a first connection member having a first end pivotably connected to the first jaw;
a second connection member having a first end pivotably connected to the second jaw;
a connecting pin assembly that slidably and pivotably connects the first and second jaws to the housing; and
a driver operably connected to a second end of the first connection member and a second end of the second connection member,
wherein longitudinal movement of the driver in a proximal direction relative to the housing moves the first and second jaws, along with the connecting pin assembly, relative to the housing from the open configuration to the closed configuration,
wherein longitudinal movement of the driver in a distal direction relative to the housing moves the first and second jaws, along with the connecting pin assembly, relative to the housing from the closed configuration to the open configuration,
wherein the connecting pin assembly extends between a first end and a second end along its length, wherein the connecting pin assembly includes a middle portion disposed between the first end and the second end, wherein the first end and the second end of the connecting pin assembly each include opposing flats,
wherein the housing comprises a forked portion including two forks, and wherein the two forks each include a slot having a cross-section that is elongated in shape with two flattened edges,
wherein the two flattened edges of each fork are configured to slidably receive the opposing flats of the first end and the second end of the connecting pin assembly, respectively, and
wherein the opposing flats are configured to slide along a length of the flattened edges.
